GAS, OIL, AND SAND SEPABATOR.

Application filed November 3, 192 1.

T 0 all whom it may concern:

Be it known that I, HARRISON M. GILL, a citizen of the United States, residing at Taft, in the county of Kern and titate of California, have invented certain new and useful Improvements in Gas, Oil, and tiand Separators, of which the following is a specification.

My invention relates to that type of an apparatus for separating gas, sand and water from oil as it comes from at producing oil well, disclosed by my Patent No. 1,490,462 dated April 15, 1924c, to which reference may be had for a more complete un derstanding of mypresent invention, which consists in a constructive improvement upon said former apparatus.

The object of my invention is to corn structively simplify the separator, both in form and cost of manufacture, While retaining all the desirable functions of the former device.

The nature of my present improvement will be fully ascertained and pointed out in the following specification and claims, reference being had to the accompanying drawings in which- Fig. 1 is a vertical sectional elevation of my separator.

Fig. 2 is a cross section on the line 22 of Fig. 1.

1 is a shell, which, by means of a plate 2 suspended therein and terminating above its bottom, is divided into two chambers 3 and 4, which chambers may be termed respectively, the initial separating chamber and the float chamber.

These two chambers communicate above through openings 5, in the dividing plate 2, the openings being guarded by a battle flange 6 justbelow them. They also communicate below at 7 under the foot of the dividing plate 2. 8 is the pipe line leading from the Serial No. MT/35H.

functions as a baflle as will presently be ex plained.

Fitted to the hcadcap 13 by means ot' a suitable stufiing box 15 is a pipe 16, the upper exterior end of which connects with the gas discharge line 1'2. This pipe 16 ere tends downwardly in the float chamber 4 to its lower end, where it communicates with a controllable oil discharge connection 18 titted across and emerging from the shell 1.

The pipe 16 is provided with a plug; or partition 16 which divides its interior into separate upper and lower portions. In the upper portion of the pipe and within the area circumscribed by the battle flange 1% are the elongated ports 19, and in the lower portion of said pipe are similar elongated ports 20, said ports providing respectively for the entrance of the gas from the chamber 4 into the pipe 16 above the plug 16, and the entrance of the oil fro-m Said chamber nto the pipe below said plug.

A sleeve valve 21 is slidably titted upon the pipe 16 and has closely fitting end collars v 22. The upper collar of the sleeve valve is adapted to control the upper ports 19 and the lower collar to control the lower ports 20 of said pipe.

A float 23 is carried by the sleeve valve 21. 24 indicates a vent tube for the float.

The operation of the separator is substantially the same as the operation of the device of my patent above refei 'rcd to. The mixed oil, gas, sand and water coming from the well through the pipe 8 is discharged into the initial separating chamber 3. The sand and water settle in the hopper-like member 11 in the lower part of the shell and may be drawn oft, at suitable intervals, through the controllable discharge connection 12.

The gas rises to the upper portion of said chamber 3, and passes through the openings 5 in the upper part of the dividing plate 2, into the tioat chamber 4.

The oil which occupies the lower portion of the chamber 3, passes under the dividing plate 2 into the lower portion of the chamber 4;. The float 23 is carried by the oil, following its level and thus moving the sleeve valve 21 up or down. If an excess of oil comes into the float chamber 4:, the float 23 rises, and the upper collar 22 of the sleeve valve 21 restricts or closes the upper or gas discharge ports 19 until the increasing volume and pressure of gas within the chamber 4c forces the excess oil out through the lower or oil discharge ports 20, thereby lowering the oil level in the chamber and permitting the float 23 to descend. On the other hand, if an excess of gas, in proportion to oil, comes into the chamber 4, the oil level therein drops, causing the float to descend until the lower "collar 22 of the sleeve valve 21 restricts or closes the oil discharge ports 20, thereby permitting the oil level to again build up.

- The function of the baflle flange 14: of the head cap 13 of the float chamber is to turn the'gas entering chamber Q downward before discharging through theupper ports 19.

It will be seen that in'the present improvement, as compared with my former device, I have consolidated the separating and float chambers in a single shell, by means of the dividing plate 2 andhave' preserved by the construction and disposition of said dividing plate, the necessary separate communications between said chambers. Also, by the construction and relative arrangement of the several controllable discharges, and the flanged head cap 13 for the float chamber 1 have simplified the device into a unitary structure, in harmony with good constructive practice and economy in manufacture.

I claim: a A gas and oil separator comprising a closed shell divided interiorly into separate chambers; an inlet connection for receiving a in the first of said chambers a mixture of gas, oil, sand and water as it comes from a well; an outlet connection from said shell for discharging therefrom the sand and water settling therein, said chambers having communications adapting the gas and oil to separately pass from the first chamber into the upper and lower areas respectively of the second chamber; a pipe within the second chamber having an upper port and a lower port communicating with the upper and lower areas respectively of said second chamber, said pipe between the ports being HARRISON M. GILL.
